Marching open stars : single pass segmentation of 3-D pseudo-manifolds

Ihle T., Fuchs S.

233-244

We present an approach for segmentation of 3D voxel data based on algebraic topology. The framework leads to a single pass algorithm for constructing symbolic descriptions of volumertic data. Unlike previous algorithms segmentation is not limited to sxtracting isosurfaces, i.e. 2D manifolds, enabling the processing of image sequences. Due to the anchoring on algebraic topology, the correctioness of the algorithm can be proven.
